Yes, that might be the idea especially for NEM 1.0, NEM 2.0 users. It gives a sort of direction and roadmap of what to do with out solar panels (besides direct usage using daytime) after NEM ended. That is if the govt does not stop ATAP when our NEM ended. Very hard to say with the current TnB and Govt.

The only thing worth about installing solar under ATAP is if you use a lot on daytime. Whatever you used directly from solar does not go to TNB thus will not be in their calculation especially for taxes. Overtime that will save a lot in such cases.

I think he is in the upper limit of generation. His area must have excellent exposure to sunlight WITH excellent panel placement AND direction, etc.
Mine 10.6Kwh with limit roof space.

They calculate RM600 to 700. I think I got average 1200kwh per month.
Based on real life usage. It generate about RM500++ each month on average. My 1 panel got shadow and most of panels are facing west. Few facing south and 1 set facing north.
So really not optimum placement.

So unless you have excellent solar panel placement and exposure, on average you better calculate as anywhere between RM500 to 600++. Don't over expect it unless the installer say your roof placement for all your panels are in EXCELLENT position to maximized generation.

Yes. No other option coz the panels are spread out wide even using the lower car porch to achieve higher capacity. Roof styling and angle really not solar panels friendly.
